Which story is the shortest story of 3 words ?

There are many type of stories long stories short stories . Some stories can only be explained only in a paragraph of a page . But there are stories which can be explained in 3 to 4 words these are the shortest stories .

Have you heard about the Six-Word Memoirs project online? They published books with six-word stories and they even have a true literary heritage:

Taking a cue from novelist Ernest Hemingway, who, according to literary legend, was once challenged to write a short story in only six words,they set out to do the same. Hemingway's six-word story read: “For sale: baby shoes, never worn.” (Wikipedia)

Jun 10 2012:
Short stories tend to be less complex than novels. Usually a short story focuses on one incident; has a single plot, a single setting, and a small number of characters; and covers a short period of time.

In longer forms of fiction, stories tend to contain certain core elements of dramatic structure: exposition (the introduction of setting, situation and main characters); complication (the event that introduces the conflict); rising action, crisis (the decisive moment for the protagonist and his commitment to a course of action); climax (the point of highest interest in terms of the conflict and the point with the most action); resolution (the point when the conflict is resolved); and moral.

Therefore by defination I am not sure that a "story" can be told in three words. As you yourself stated "stories that can be explained in three or four words ...." So these are explainations not stories.
